Patient interface with venting

Abstract

Interfaces for positive pressure therapy having various vent designs are disclosed herein. The interfaces include a bias flow vent with design geometries that help reduce and / or minimize draft and noise levels of the fluids exiting the vents. Some of the vent designs include particular vent hole geometries, plenum spaces, diffusers and fibrous media.

Description

INCORPORATION BY REFERENCE TO ANY PRIORITY APPLICATIONS[0001]Any and all applications for which a foreign or domestic priority claim is identified in the Application Data Sheet as filed with the present application are hereby incorporated by reference and made a part of the present disclosure.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention generally relates to patient interfaces for respiratory therapy. More particularly, certain aspects of the present disclosure relate to various systems and methods for venting gases from patient interfaces.[0004]2. Description of the Related Art[0005]The treatment of obstructive sleep apnea (OSA) by continuous positive airway pressure (CPAP) flow generator systems involves the continuous delivery of pressurized gases to the airways of a human via a conduit and an interface (e.g., a mask). Typically the interface creates at least a substantial seal on or around the nose and / or the mouth. As the patient breathes...

AI Technical Summary

Benefits of technology

The patent text describes a configuration where a male coupling has multiple passages formed on its male portion to prevent blockages at extreme movements. These passages prevent the coupling from being completely blocked, even when it reaches its maximum speed.

Problems solved by technology

As the patient breathes, carbon dioxide gases can progressively accumulate in the delivery system, which if left over a period of time, can become hazardous to the patient.

The vents can create a disturbance for the patient and / or the patient's bed partner.
